What is CVE-2026-14852?
CVE-2026-14852 is a medium-severity command injection vulnerability in Checkmk, published on 14 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Privilege escalation in Checkmk versions 2.5.0 before 2.5.0p9, 2.4.0 before 2.4.0p34, 2.3.0 before 2.3.0p49, and 2.2.0 (EOL) allows a local unprivileged user to execute arbitrary commands as root by starting a process crafted to look like a SAP HANA instance. Without an explicit database configuration, the mk_sap_hana agent plugin derives instance identifiers from the process list and uses them to build a command executed with elevated privileges (requires the plugin to run as root with RUNAS=agent).
